Aled Jones is on the Isle of Man to discover how the roots of Christianity stretch back over 1,500 years.

He visits Cathedral Isle of Man and learns about the story of Saint German of Man. Aled also discovers how the rich Christian history of the island is portrayed in the cathedral's unique, interactive gardens.

Further afield, Aled meets a Christian shepherdess and her flock to hear about a rewilding initiative in a local church's grounds. Then at Café Lingo, he learns about an English language teaching enterprise led by a methodist church to help new arrivals to the island, with an ethos inspired by the Bible's stories of welcome.

Back at the cathedral, Aled meets some of the volunteers who tend to the gardens and hears how faith influences their work and what made them to want to help.

Katherine Jenkins joins celebrations at the Roman Catholic cathedral in Arundel, West Sussex, marking the Feast of Corpus Christi. The festivities include a spectacular carpet of flowers and a procession from the cathedral to the castle.

Katherine meets the Duke of Norfolk, who explains the legacy of his relative, the 15th Duke, who introduced the beautiful floral custom to Arundel over 140 years ago. And we hear from the flower carpet designer about the symbols in this year's display.

Bishop Richard Moth explains the spiritual importance of Corpus Christi, which for Catholics is a celebration of the presence of Jesus in the Eucharist, and Katherine meets some of those participating in the procession, including a child who has recently taken her first Holy Communion.

At Arundel Castle, we revisit the time Katherine met a gardener whose faith has been instrumental in her life and work.

With music that celebrates the Eucharist and an a cappella performance from vocal harmony group Stellina at Blenheim Palace.
